Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601722, here are decompositions:

11 + 31601711 = 31601722
23 + 31601699 = 31601722
71 + 31601651 = 31601722
233 + 31601489 = 31601722
311 + 31601411 = 31601722
839 + 31600883 = 31601722
863 + 31600859 = 31601722
1019 + 31600703 = 31601722

Showing the first eight; more decompositions exist.
